What a sad story.
Suicide and assistance of suicide and even incitement to suicide (with certain exceptions like conning somebody into commiting suicide with false information or not assisting somebody who is unconscious and of whom you do not know if they seriously intended to kill themselves, especially as a paramedic, etc.) are legal here in Germany and apparently what he did would be absolutely legal here.
I think the right to end your life is an essential part of human dignity and self determination, but one that should not be toyed with lightheartedly (I just saw a story about a 13 year old Romanian teenager who killed himself because his parents did forbid him to use the computer!!!). That clearly wasn't the case here.
